Real life gets tough. It's not easy. We condition to become stronger, to build up what we call body armour. Crawling is one way we prepare our bodies for our jumps and yes, our falls too. Everyone will fail and fall eventually, it is but a matter of time. The more body armour we have, the less we will be hurt by these falls. It is also a way for us to learn to push through struggles and to find that "something" within ourselves to continue through hard times.
It is our job as Parkour/ADD instructors to get younger students ready for real life, and to give older students a way to get through it. To teach them that we must not give up, to teach them that effort produces results. We must show them that they are capable of much more than they think they are. Give them confidence in every day life so that they do not have to fear what others think of them, what others say of them.
Parkour & Art du Déplacement training can and should allow you to build and discover strength, in every sense of the word.
